Lethal Performance of Texas

"This is what 11+ thousand dollars and 9 months of work from lethal performance looks like. Horrible Tak welds and they drilled tak screws into my body to hold my side sills on my VIPER they didn’t insulate anything at all and in the 9 months they didn’t call me once…. Not once. They didn’t give me any parts back including a 1000$ water pump, cam that was taken off the car and refuse to call me back or give me my part back anyone that’s taken their car there take a look at their work I was baffled that a shop this size does work like this and provides absolutely no customer service."

"Needed a price on how much it would be to measure, order and installing pushrods, getting a tune and lining up my exhaust due to the F710 heads being a 1/2 inch taller than stock casting heads. Was told to send an email and never got replied to. Customer service needs to be improved drastically."

"Easily the best shop in the country when it comes to anything Chevy/LS/LT. Brought my C6 ZR1 in after having work done at HPC in Houston. Wanted to have them Tune the car and they found some things that saved me. Pricing is super reasonable and the quality of work is superb. Cannot recommend these folks enough. Fantastic shop and I’ll be sure to be back in the future. PS! Thank you JP for recommending these folks. They know their way around the ZR1."

"Well I ordered a few parts from Lethal because of their videos of the 24 Mustang, and my recent purchase. I ordered the backseat delete and black badges, that is all. 3 days later I order some other items for my mustang from Steeda than 2 days later I ordered more items from Steeda. 3 weeks later I have all my items from Steeda and still no tracking number from lethal. Never again guys. Stick to Youtube."

"Recently moved here from Georgia.I have a lot of chevys. Having trouble with a small evap leak on my colorado. Regular shop followed the code replaced the vapor canister and a few other things, eventually said it was coming from seal from my aftermarket supercharger they recommended this place. Explained all this to the guy at the front and couple of times. After a few weeks I got my truck back….they just replaced the vapor canister….again…for 500$. Check engine light back on after a few days. Would not recommend this place for anything other than what they do every day which seems to be tuning corvettes. Super clean shop. Seem organized but this job was definitely not for them. I want to put fuel injection on my 67 Camaro and 71 blazer and my guess is they would do a good job here but I’m going to look elsewhere"
